SPECIFICATION forming part of Letters Patent No. 677,034, dated June 25,1901. Application filed tober`24, 1900- Serial No. 34,199. (No model.)

To all whom, i may concern:

Beitknown thatLGEORGE L. KNAPP, a citizen of the United States, residingat Northfield, in the county of Rice and State of Minnesota, haveinvented certain 'new and useful lmprovements in Lamp-Burners; and I dohereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and use the same.

This invention relates to burners for lamps using oil as aflame-supplying medium, and is designed to minimize the casualtiesgenerally resulting from fire and explosion when the lamp overturns,tilts, or falls to the floor.

For a full description of the invention and the merits thereof, and alsoto acquire a knowledge of the details of construction ofthe means foreffecting the result, reference is to be had to the followingrdescription and drawings hereto attached.

While the essential and characteristic features of the invention arenecessarily susceptible of modification, still the preferred embodimentof the invention is illustrated in the accompanying drawings, in which-Figure l is a vertical central section of a lamp-burner embodying theinvention, the extinguisher being held out of the Way of the flame. Fig.2 is a perspective view of the burner, the cone being omitted and theextinguisher closed over the wick-tube. Fig. 3 is a perspective view ofthe weighted catch, its pivotal mounting, and a portion of the gallery.Fig. et is a detail view in perspective of the extinguisher and itsspring-support.

The burner illustrated is of common construction and is shown todemonstrate the application of the invention, and consists, essentially,of the base l, gallery 2, wick-tube 3, and cone Li.

The safety appliances consist of the extinguisher 5 and weighted catchor detent 6. The extinguisher 5 is an oblong plate transversely curvedand positioned to fit snugly over the end of the wick-tube 3 when theflame is extinguished. A stop 7 is provided centrally of theextinguisher and adapted to be engaged by the hooked end S of the catch6 when the extinguisher is held out of the way of the flame, as shownmost clearly in Fig. l. The extinguisher is connected with the galleryby means of a spring-support composed of a pair of similarly-formedelement-s, each comprising a vertical arm 9, a horizontal arm lO, andaseries of coils l1, intermediate of the two arms. The parts 9, 10, and1l are integral portions of asingle length of spring-wire bent into theform'substantially as shown. The vertical arms 9 are soldered orotherwise secured to one side of the extinguisher 5, and the horizontalarms l0 are similarly att-ached to the gallery 2. The coils l1 extendinward from the vertical arms 9, and the horizontal arms l0 are attheinner ends of the said coils. The coils are held in alinexnent by meansof a pin l2, passed therethrough and having its ends upset to preventcasual displacement. The coils ll, with the pin l2, fit as close in theangle between the wick-tube and the gallery as possible, so as to be outofthe Way and enable the parts to be compactly disposed. The weightedcatch or detent 6 is formed of a single length of stout Wire bent toprovide an eye 13, by means of which it is pivotally connected with thegallery. The upright portion of the detent or catch extends through anopening 14, formed in the gallery 2, and its lower portion curvesoutwardly and receives the weight l5. The coilof the Wire forming theeye 18 lies adjacent to the under side of the gallery 2 and is held inplace by a hanger 16, consisting of a length of wire bent into U formand having its legs passed through openings in the gallery and bent inopposite directions to hold the parts against accidental displacement.When the lamp is burning, the extinguisher is held out of the flame, asshown in Fig. l, by means of the stop 7 thereof, engaged by the hook 8.In the event of the lamp overturning or receiving a severe jar theweight l5 will react and release the hooked end S of the detent from thestop 7, when the extinguisher will move under the inuence of itsspring-support and close upon the upper end of the wick-tube andextinguish the flame and prevent contact thereof with the oil or otherinflammable article coming within its range. The safety appliances areof such construction as to be applied to any malte of burner Withoutreq'uiring any special change in construction a-nd can be applied by theaverage person, thereby placing upon the market means for IOO thepurpose aforesaid exceedingly cheap,easy of application, and effectivein operation.

Having thus described the invention, what is claimed as new isl. Incombination with a lamp-burner, an extinguisher having a stop, aspring-support connecting the extinguisher with the gallery, a weightedcatch or detent formed of a length of wire bent between its ends toprovide an eye, the upper portion of 'the detent passing through anopening in the gallery and formed with a hook to engage with the stop ofthe extinguisher and the lower portion of the detent curvingoutwardlyand weighted, and a U-shaped wire looped into the eye of thedetent and having its side members passing through/the openings ofthegallery and bent, substantially as specified.

2. In combination with a lamp-burner, an extinguisher provided with astop, a spring support consisting ot' similarly-formed parts,

yeach constructed of a single wire bent to prothe stop of theextinguisher and having its Y lower portion curved outwardly andweighted,

'and a U-shaped wire looped into the eye of the catch and having itsmembers passed through openings in the gallery and bent to retain theparts in position, substantially as set forth.

In testimony whereof I affix my signature in presence of two witnesses.

F. O. RICE, A. I. DRAKE.
